Patients presenting with undifferentiated respiratory distress remain a diagnostic dilemma. The use of point-of-care ultrasound (POCUS) to evaluate the lungs and pleural cavities can improve diagnostic uncertainty in these patients. When visualizing consolidated lung tissue with POCUS, one may encounter static or dynamic air bronchograms. Static air bronchograms are seen in atelectasis and pneumonia, whereas dynamic air bronchograms are highly specific for pneumonia. We describe a case of a critically ill patient where bedside thoracic ultrasound helped to narrow the differential diagnosis early in the resuscitation, while standard radiographs were non-diagnostic.
表现为未分化型呼吸窘迫的患者仍然是一个诊断难题。使用床旁超声（POCUS）评估肺部和胸腔可以减少这些患者的诊断不确定性。当用POCUS观察实变的肺组织时，可能会遇到静态或动态的空气支气管征。静态空气支气管征可见于肺不张和肺炎，而动态空气支气管征对肺炎具有高度特异性。我们描述了一例危重症患者，床边胸部超声有助于在复苏早期缩小鉴别诊断范围，而标准X线片无诊断价值。
